MACHINE FOR COATlNG THE INTERIOROF VESSELS WITH WATER-PROOF LlNlNG.

SPECIFICATION forming pari'. of Letters Patent No. 360,952l dated April12, 1887.

Application tiled March 3, 1886. Renewed December 13, 1886. Serial No.221.421. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. CEowELL,

a citizen of the United States, and a resident `of Rogers Park, in thevcounty of Cook and State of Illinois, have invented certain new.

l shall be so constructed and arranged that it will impart to the vesselan even and uniform coating and without anyloss or waste of the coatingmaterial.

A further object is to so construct a device of the character set forththat vany number of vessels may be treated at one time and without'injury from the machine and Without smearing or defacing their outersurfaces with the coating substance.

A further object of my invention is to provide a machine for coating theinterior of vesselswith a water-proof lining which shall com binesimplicity and economy in construction with durability and efficiencyin'use.

vIn the accompanying drawings, Figure l is a view of my improved devicein perspective, a number of the bottles or vessels being removed fromthe top of the reservoir for the purpose of showing the nozzles or vents3 5 through which the material is passed into the vessels; and Fig. 2 isa modification. A represents a frame constructed in any suitable mannerand adapted to support the reservoir B, which is preferably made of 4ometal and provided on its ends with the shafts a, adapted to fit inbearings on the frame A. This reservoir is constructed of any suitablesize or dimensions and adapted to contain the material with which thevessels are internally coated. The top of the reservoir is provided witha number of small nozzles" or vents, b, extending upwardly andpreferably,

funnel or cone shaped, arranged in rows and at suitable intervals apart.To one end of the constructed of the horizontal pieces cZ-and the endpieces, e. The hinges are preferably secured to the end pieces, e, andextend through the vertical elongated slot-s formed Vin the standards c,and are held rigidly therein by means of the thumb-screws f, which, whenadjusted, impinge against'the standards. By means of' this constructionit will be readily seen that by proper manipulation the follower C maybe adj usted toward or away from the top of the reservoir and heldrigidly in any desired adjustment. On the opposite side of the reservoirare secured the standards g, to which the free end of the follower Cmay, when in proper position, be locked in any suitable manner.

D represents the boxes, bottles, or vessels to be treated, which, aswill be seen by reference to the drawings, are inverted and placed uponthe cone-shaped nozzles or vents b, the latter extending up into thevessels, into which they fit, thus preventing any leakage or escape ofthe material during the operation of lling the vessels and avoiding anysmearing or defacing of the outer sides or surfaces thereof.

v To the under side of the follower C are secured the coil-wire springsE, so arranged that when the follower is in its normal or horizontalposition they will press upon the bottoms of the vessels and therebyoperate to hold the latter tightly on thenozzles b. A further functionof these springs is to compensate for irregularities in the length ofthe vessels or bottles. By vertically adjusting the follower withreference tothe reservoir, vessels or bottles of different sizes4 may betreated and the tension or pressure of the springs upon the same beeasily and readily regulated.

To one end of the reservoir Bris connected a steam-pi pe, by means ofaiiexible pipe or coupling, h, said pipe or coupling being constructedof flexible material for the purpose of allowing the rotation or partialrotation of the reservoir, as hereinafter described.

Within the reservoir the steam-pipe is constructed of metal,outletvpipes being provided in connection with the above for the purposeThe function of the steam admitted into the pipe or pipes within thereservoir is to keep the coating material within the latter in a liquidstate, or of such consistence as will permit it to freely and readilyflow through the nozzles into the vessels. Instead, however, ofemploying steam as a heating agent, as above described, the device maybe constructed to operate in the manner indicated in Fig. 2, wherein isshown a fire-box or heater, J, located below the reservoir, whereby thematerial, in consequence of the heat applied bclow the same, will bekept in the proper condition as before. In such cases, where the heatisimparted from below, it is desirable, and even necessary, to move thereservoir to a position where, when the latter is inverted, the tirewill not come in contact with the vessels being treated. I havetherefore pivoted one of the trunnion-bearings to the frame A, and atthe opposite end of the reservoir provided a circular track or bearing,1', whereby one end of said reservoir may be moved around to such anextent as to relnove the same a sufficient distance from the fire, thetrack serving as a bearing or support for the shaft or trunnion on theend of reservoir and operating to hold the same in a horizontalposition.

After the vessels to be treated have been properly arranged 011 thenozzles the follower is lowered and clamped tightly in position, thesprings bearing on the bottoms of the vessels, and the reservoir theninverted or partially rotated by means of the crank k, formed on theshaft c, or by other suitable means, and held in that position until thevessels have been lled with the material, the length of time requireddepending upon the size of the vessels.

If the device shown in Fig. 2 is employed, the use of which I wouldrecommend, the reservoir, as before stated, is moved around to aposition at a sufficient distance from the fire vand the operation thencontinued, as in the abovedeseribed machine. The reservoir,after -havingremained in its inverted position a suitable length of time, is thenrighted,and the material contained in the vessels allowed to flow backthrough the nozzles into the reservoir. The follower can then be raisedand the vessels removed from their positions on the nozzles, and, afterhaving stood for a few minutes to allow the coating on the interiorthereof to harden, are in condition to be filled or otherwise disposedof.

It is essential that the material within the reservoir be kept in aproper condition, and I have therefore found it desirable to attach athermometer, l, to the reservoir for indicating the temperature of thecontents thereof, in order to avoid the danger of allowing the materialto become too hot, in which ease it would operate to injure the materialof which the vessels are constructed, or of allowing it to become toocool, in which case it would not readily flow into the vessels norproperly adhere to the interior surfaces thereof. I have also found itdesirable to provide the nozzles with valves, which, when only a portionof the nozzles are used, may be closed to prevent .the escape of thematerial from those not in use when the reservoir is inverted.

The top of the reservoir is provided with an opening, in or on which isfitted a plug or cap, m, and through which the material is passed,preferably in a liquid form, being first heated to the proper degree ina separate reservoir (not shown) provided for-the purpose.

The side of the reservoir is provided with an air-cock, l11which, whenthe reservoir is inverted, is opened to allow the ingress of air andfacilitate the filling of the vessels.

From the above description it will be readily seen that my improveddevice may be so constructed that any number of vessels and of any sizeor dimensions may be treated at one time, and that, although very simpleand economical in its construction and arrangement of parts, itoperates' to line or coat the interior ot' the vessels without any lossof material and without in the least degree injuring or defacing theouter surface thereof from the escape or leakage of the material.

It is plain that the mechanical features may be varied in manyunimportant respects without changing the result of their operation; andit is also plain that the appliances for heating` the contents of thereservoir may be used or not, as preferred. Thus the reservoir may befilled with a liquid and the vessels attached and coated the same aswhen the liquid condition of the coating material is the result of theaction of heat.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-
